Testing of peats for removal of odors from liquid swine manure
January 1, 1998
This paper reports on research designed to investigate the capacities of different kinds of peat to remove odor-causing compounds from liquid swine manure (LSM). Two experiments were conducted. In...
Odor reduction bioreactor system
January 1, 1998
A laboratory scale odour reduction bioreactor system was designed and developed to provide initial evaluation of kenaf (Hibiscus cannabis) as a potential attached growth media for odour abatement and wastewater remediation of swine wastewater.
Outdoor hydrogen sulfide concentrations near a swine feeding facility
January 1, 1998
Ambient hydrogen sulfide concentrations were monitored for several months at the property line of a wean-to-finish swine production facility. Data was analysed to determine apparent influences of...
Volatile fatty acid emission during composting of swine waste amended with sawdust as a measure of odor potential
January 1, 1998
Offensive odours which evolve during the decomposition of swine waste have resulted in complaints from neighbours in agricultural areas. This study chronologically monitored the emissions of volatile...
An inflatable cover for a concrete manure storage in a swine facility
January 1, 1998
This study demonstrated that an air supported inflatable manure storage cover could be an economical and effective method for reducing odour emission into the atmosphere. To construct this inflatable...
Ammonia emissions from composting hog manure amended with sawdust under continuous and intermittent aeration
January 1, 1998
Ammonia emissions during composting of hog manure mixed with sawdust were studied in four runs comprising a total of 22 pilot-scale reactor vessels. These four runs extended previous work and both...
Production of odorous, volatile compounds during composting of hog manure amended with sawdust
January 1, 1998
Gas chromatographic analysis of volatile fatty acids (VFAs) in mixtures of swine manure and sawdust and in condensate samples of gasses emitted during composting of these mixtures was conducted. Two...
Measurement and analysis of atmospheric ammonia emissions from anaerobic lagoons
January 1, 1998
Ammonia-nitrogen flux (NH3-N = (14/17)NH3) was determined from six anaerobic swine waste storage and treatment lagoons (primary, secondary, and tertiary) using the dynamic chamber system....
Carbon dioxide and nitrous oxide emissions following fall and spring applications of pig slurry to an agricultural soil
January 1, 1998
In Quebec, Canada, most pig slurry is applied to agricultural soils in the spring and fall. A study was initiated to compare the impact of the contrasting spring and fall weather conditions on CO2...
Odorous emissions and odor control in composting swine manure/sawdust mixes using continuous and intermittent aeration
January 1, 1998By David L. Elwell
Swine manure mixed with sawdust was composted in 205 L pilot-scale vessels. Four runs with a total of 22 vessel studies were made during 1998 and 1999. Composting was conducted, with either...
Separation distances for swine odor control in relation to manure nutrient balances
January 1, 1998
One approach to odor abatement at swine facilities is to provide adequate buffer zone or separation distance from neighbors. Use of a nutrient (nitrogen and phosphorus) balance to determine land...
Single-component modelling of pig farm odour with statistical methods and neural networks
January 1, 1998By Simon X. Yang
Pork farm odour has become an increasingly important problem for the pork industry because non-farming rural residents object to the odours coming from pig facilities and insist that it disrupts...
